T0 alt whom it maa concern) c Be it known that I, ALBERT-H; DE Von,

a'citizen of'the 'UnitedStates,v residingat VVestfield, in the county of Union and State of New Jersey, havefinvented certain new and useful Improvements in Bearings and Oiling Means Therefor, of which the following is a specification, reference being had therein to the accompanying drawings.

V This invention relates to a bearing and oiling means for rotating parts, and more particularly to the bearings for the pulley- ,wl1eols' of a power-transmitter, such as shown in my copending application Serial No. 225,935, filed April 1, 1918, of which this is V a division.

' The objects of thei nvention' are'to pro vide a simple, compactand efficient bearing.

means for rotating parts, and to provide for the certain, efficient, and economical lubrication of the bearin 'm'eans. p I

The invention in a pre erred form, and as applied toa power-transmitter, comprises a hanger having a projectingbearing stud, an

oil-well carried by "the hanger, driving and drlven pulley-wheels, the former having a I running bearing on'the exterior of the stud and a thrust-bearing within said'vveljl, and the latter having a running bear ng on the interior of the stud. Means. are provided; for supplying oil from the Well to the exterior running'bearing, and ducts leadthe oilfrom theexterior bearing to the interior one, thence to thethrust bearmg and back to thewell. V p

In the accompanying drawings, the figure is a side elevation of a power-transm1tter,

partly in section, showing the bearings for the pulley-wheels'andthe means for'oiling them. I

Referring to the drawings, 1 indicates a tabletop having secured to its lowerside the bracket 2 from which depend a lug 3 and spaced lugs 4. A rod 5 is fixed in the lug 3 and a rod 6 is slidably mounted inthe lugs 1. A hanger frame 7 is adjustably secured to the rod 6 by a set-screw 8 which engages screw threads (not shown) on the rod. The frame 7 also has a lug 9 with a channel or fork 10 which latter sli'dably engages rod 5. By means of a cam-lever 11 the hanger may be shifted on rod '5 in the manner fully explained in;my,copending application, above mentioned. The hanger has Specification of Letters Patent; Patenteel- Oct, 1921, I Original application ledA ri1'1,191s,'s eria1 mamas; Di ided at this application fi1ed 0etotei-'30,

depending arms 12 r and v 13 "'channelshapet A tubular bearing stud 14 is fixed at one end 'in 'a bushing 15 secured in the lower end' of the hanger arm 12, the other end of the stud being free. Mounted on theexterior sur face of the stud is the tubularhub-16 ofthe driving pulley 17 of the transmitter, the

pulley being connected by a belt 18 with the usual constantly running line shaft, not Q shown. The driving pulley is formed with an annular friction driving surface19. The, hub 1611s confined agalnst ax al movement by a c llar 20 atone sideand a ball-thru t bearing at the o h Side- The driven pulley 22 isconnected'by a belt 23- to the,

machine to be driven, and is'fiiged toa stubshaft 24; journaled Within the "bearing stud face 19r on pulley 17. 'Th'e*driven pulley is alsoprovided with a friction surface% on the side opposite the friction ring 25. A

bralte-fdisk A is fixed in the hanger by a hub 28 and, Carries a leather' friction ring '29 of I large I diameter complementary to ith tion Surface 26,

Means; are providedto shiftthe driven pulley as followsa rock-shaft 30 is act-uated by a ti'eadle mechanisinlfnot shown) asmore fully disclosed in my ,copen-ding application; Depending from opposite; ends of the rock-shaft are armsf31 and 32 can ryingl cam-surfaces 33 and 3 1 at theirlower- These cam surfaces are parallel,,but inclinedto the axis of shaft- 2 i, and engage puslr'pins 35 and36, which latter".

extremities are in engagement withth'erespective ends offshaft 24L When" the rock shaft is rotated" in one direction the pushpin 36 is actuated to move the driven pulley into engagement;

with the driving pulleyhw'hile when the rock-shaft is rotated in the opposite 'direc tion the pusli-pin 3 5,is actuated to move the driven pulley into engagement with the brake.

At the lower end of the hanger arm 12 is formed an oil-well 87 which surroundsthe' Welland a series of oil inlets39 lead from the groove to the interior of the hub. Hung in'the groove is an oiling ring 10, 'Anml distributing groove 41 is formed on the exterior surface of the bearing stud 14: and

communicates with the inlets 39. Oil-ducts: 42 lead from the groove 41 to the interior surface of the bearing study and an oil-duct 43 leads from the interior of the stud to the ball-thrust bearing 21.

' In the operation of the transmitter eil is carried by the ring 40 from th'e Well'37 to the inlets 39 in the hub and flowing along the groove 41 lubricates the bearing of the driving pulley. The oil then flows. througl ducts 4-2 to the interior of the bearing stud and 'lubricates the bearing of the driven pulley, and finally flows byvvayot duct 43 to the ball-thrust bearing and back to the I ell.

' Havingthusset forth the nature of the invention, What I claim herein is 1. In a power-transmitteigin combination,

a hanger formed with an oilell, driving and driven members supported by said hanger, running and thrust bearings for;

said-members, and ports for conducting the 011 to said bearingsin IS61'16S and lastly rea turning thessurplus oil to the oil-well, and

means for 'conductingthe oil from the Well to the ports leading tooneof the bearings whereby the oil passes through each of the various bearings of thetransmitter and then a returns to the supply in the Well. i

2. In a power-transmitter; in combina-.

tion a hanger formedwith" an oil-cavity including an'oll-vvell, a tubular stud carried by said hanger, a dmi g' uile journaled on the exterior of said stud,l a collar and thrust bearing for fixing the Working post tion of said driving pulley onlsaid stud, saidthrust bearing being located Within said oil-cavity, a driven pulley journaled within said stud, meansfo'r conducting the oil from the oil-Well to the external bearing, vsaid tubular stud being provided With a'port for conducting the oil from the external to; the internal bearing, and a port for conducting the oil from the internal to the ball thr'ust bearing from whence Well.

3.,In combinat/ion, fwheels hav'ing concentric bearings athrust-bearing for one of said Wheels, an oil-Well, and means for Suecessively feedlng 011 from said Well through it returns to the oilsaid concentric bearings, the thrust-bearing,

and bach to the Well.

4. In combination, an oil-Well, a bearingstud projecting therefrom, pulley-Wheels having bearings exteriorly and interiorly' of "said stud, a thrust-bearing for one of said Wheels, and means for circulating oil from Wheel mo table on said interior bearing surface, and means for oiling said bearings in series from said Well and returning the oil to the ell.

6.
